Effective May 18, 2026
By using modus-vivendi.ai or Old Growth Longevity (OGL), you agree to these terms. If you don't agree, don't use the services.
Old Growth Longevity is a coaching and tracking app that synthesizes longevity science into personal guidance. It is not a doctor. It is not a substitute for medical care, diagnosis, treatment, or prescription. The coach will sometimes share information drawn from research; that information is educational, not clinical advice.
You are responsible for your own health decisions. Talk to a qualified medical professional before starting new exercise programs, changing your diet, taking supplements, or making other health changes — especially if you have existing conditions, are pregnant, or take medication.
Founding Grove acceptance is at our discretion. We may extend, decline, or revoke invitations. Founding terms — including any pricing or feature commitments — apply only to members in good standing and may be defined more fully at the time of invitation.
Don't use our services to harm yourself or others, to violate laws, to misrepresent your identity, or to attempt to extract data, scrape our infrastructure, or circumvent security. We may suspend or terminate access for any of the above.
All content, branding, code, and design on modus-vivendi.ai and within Old Growth Longevity are owned by Modus Vivendi unless explicitly noted. You may not copy or redistribute without written permission.
The services are provided 'as is.' We make no warranty that the services will be uninterrupted, error-free, or that the information will be accurate for your specific situation.
To the maximum extent permitted by law, Modus Vivendi will not be liable for indirect, incidental, or consequential damages arising from your use of the services. Our total liability for any claim is limited to the amount you have paid us in the prior twelve months, if any.
We may update these terms. Continued use of the services after changes constitutes acceptance of the new terms.
